# Use Cases

> Warp Bridge offers API, widget, and smart contract integrations for easy, secure cross-chain transfers.

## **Integration Overview**

**Warp Bridge offers several integration paths depending on your product’s needs. Whether you’re building a wallet, dApp, exchange, or backend service, you can integrate Warp Bridge through our API, widget, or smart contracts.**

**Below is a streamlined overview of each option.**

## **Warp Bridge API**

**Recommended for most production integrations**

The API is the most flexible way to add cross-chain transfers. It abstracts routing, pricing, execution, and multi-chain infrastructure so you can focus on user experience.

With simple REST endpoints, you can quote swaps, submit transfers, track status, and manage lifecycle events.
